Point having an Integer index reference number metadata about the LandInfra dataset user defined unique ID used to identify a LandInfra dataset or file extension of 19148/Topic 19 LinearElement Type, adding optional Referent(s) real number in the range of -100 to +100, where 2.00 = 2% A PolyfaceMesh consists of one or more SimpleIndexedPolygons. A SimpleIndexedPolygon has at least 3 sides. These SimpleIndexedPolygons are defined by a list of at least three Index values. Each Index value represents an IndexedPoint which contains the index and a list of coordinates. The list of eligible IndexedPoints used by a PolyfaceMesh is contained in the PolyfaceMesh definition. if not specified, defaut is 1 (one). Can use either * or n for unbounded An extension to ISO 19148, this subtype of Referent allows for the specification of a restart measure value at the Referent location for use by all linearly referenced locations which include this referent and use the specified LRM, similar to the startValue of a LinearElement. Together with the Referent Location, this restart value can be used to specify a station equation Simple Polygon Surface defined by IndexedPoint indices
